  • Equivalent Models List(mouse over to view pertinent information):Below is a model equivalency list which identifies OEM machines (in bold / blue) that are sold by other companies under their own brand names. Typically, troubleshooting / error codes / machine parts are identical, but some may be modified to the re-branded company’s specifications by the OEM – you will want to verify this when purchasing parts from your parts supplier. Toner, cartridges, and other consumables may not be identical, so you will want to make note of this when purchasing these products.
